Determination of Pulse Oximetric Parameters of the Body by Photoplethysmography

A sharp increase in respiratory tract morbidity, including from coronavirus infection, increases the need for individual means of continuous diagnosis. Currently, such devices as pulse oximeters are widely used. With their help, the heart rate and arterial blood oxygen saturation are monitored, which makes it possible to respond in a timely manner to the deterioration of the human body. The principle of operation of pulse oximeters is based on the method of photoplethysmography. The development of medical devices, including pulse oximeters, using modern technologies is an actual direction of radio electronics and allows to achieve high accuracy, efficiency, reduction of dimensions and ease of use of these devices. © 2022 IEEE.
